Gold Knife Edition cushioning pad for the floor: Coordinated with the knife line, maximizing the overall efficiency of the die-cutting system.

In the printing and die-cutting production process, many enterprises fall into a common misunderstanding: in an attempt to enhance the die-cutting effect, they upgrade the imported blade lines at a high cost, but still frequently encounter problems such as burrs, consecutive dots, blade line fractures, and low yield rates. In fact, the die-cutting system is an organic whole. The coordinated matching of the blade line and the blade plate spring pad is the core factor determining the quality and efficiency of die-cutting. According to industry statistics, over 70% of the premature wear of the blade lines is caused by the mismatch between the spring pad and the blade line, resulting in the embarrassing situation of 1+1 < 2. Tongzhongjin has深耕 the die-cutting consumables field for many years and has broken the traditional model of "selecting blade lines and spring pads separately"， creating an integrated collaborative solution for blade lines and spring pads， maximizing the overall efficiency of the die-cutting system.

The coordinated matching of the blade line and the blade plate spring pad follows four golden principles， and any deviation in each step will directly affect the production effect.

First， the hardness coordination principle： soft blades with soft pads， hard blades with hard pads. The hardness of the blade line and the hardness of the spring pad must form a precise match to achieve the best buffering and supporting effect. Ordinary high-carbon steel blade lines (HRC52-56) are suitable for邵氏 35-45 度's medium soft spring pads， which can provide sufficient buffering protection for the blade line and ensure thorough cutting； alloy tool steel blade lines (HRC58-62) are suitable for邵氏 50-60 度's medium hard spring pads， with stronger supporting force， suitable for medium-high speed die-cutting； powder metallurgy high-speed steel blade lines (HRC63-65) are suitable for邵氏 60-70 度's high-hard spring pads， capable of withstanding the strong impact force of high-speed pressing and avoiding blade line fractures. At the same time， the blade spacing also determines the hardness of the spring pad： when the blade spacing is less than 8mm， a medium-hard spring pad is selected to prevent blade gap collapse； when the blade spacing is greater than 8mm， a soft spring pad is selected to ensure gentle rebound. 

Second， the height coordination principle： the height of the spring pad is about 1.2mm higher than the blade tip. The height of the spring pad directly determines the die-cutting pressure and rebound effect. If it is too high， it will cause insufficient die-cutting pressure and incomplete cutting； if it is too low， it will not effectively buffer and damage the blade line. The technical team of Tongzhongjin has conducted over ten thousand tests and verifications， and 1.2mm is the optimal height for the spring pad above the blade tip. It can be adjusted slightly based on the hardness of the spring pad： for low-hardness spring pads， it can be appropriately raised to 1.3-1.4mm， and for high-hardness spring pads， it can be lowered to 1.1-1.2mm.

Third， the lifespan coordination principle： replace the blade line and the spring pad simultaneously. Many enterprises， in an attempt to save money， only replace the blade line when it becomes blunt without replacing the spring pad. However， they do not realize that the surface of the worn spring pad has formed knife marks and grooves， which will accelerate the wear of the new blade line， resulting in a 50% or more reduction in the lifespan of the new blade line. The correct approach is to check the condition of the spring pad at the same time when replacing the blade line， and if there are obvious grooves on the surface of the spring pad or the rebound slows down， it must be replaced simultaneously to ensure that the new blade line performs at its best.

Fourth， the arrangement coordination principle： the blade lines are symmetrically arranged on both sides， with a spacing of 1-2mm.
